WARP-BEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 664,335, dated December 18, 1900.

Application filed January 31, 1899. Serial No. 703.956- (No model.)

To all whom it may concern.-

Be it known that 1, DAVID MCTAGGART, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Warp-Beaming Machines, of which the following is a specification, accompanied by drawings, forming a part of the same, in which- V Figure 1 is a top view of a Warp-beaming machine embodying my invention. Fig. 2 is an end view. Fig. 3 is a sectional view on Fig. 4 is a rear view of the counter-shaft and connected gearingby which a change of speed of the warp-beam is obtained. Fig. 5 represents a portion of the framework holding the rocking shafts, with a side view of one of the adjustable bearings which support the rocking shaft carrying the warp-compressing roll. Fig. 6 is a side view of one of the adjustable bearings, showing the opposite side from that represented in Fig. 5. Fig. 7 is a detached view of the ratchet-wheel and retaining-pawl by which the reverse motion of the warp-beam is checked. Fig. 8 represents a sliding block carrying the lower pulleys, with its track and actuating-screw, shown in sectional view on line 8 8, Fig. 1; and Fig. 9 is a central sectional View of the friction-rolls in contact with the warp-compressing roll.

Similar reference letters and figures refer to similar parts in the diiferent views.

My invention relates to that class of warpbeaming machines in which a warp-compressing roll is held in contact with the warp as it denotes the bed or that portion of the framework upon which the warp-beam is mounted and upon which are the supporting-brackets 2 and 3, provided with journal-bearings for a hollow shaft 4:, and a bracket 5, which is adjustable along the bed 1 to accommodate warp-beams of different lengths.

The warp-beam comprises the heads 6 and 7, connected by a barrel 8, upon which the warp 9 is wound, and having a gudgeon 11 journaled in the bracket 5 and a gudgeon inserted in the hollow shaft 4. The head 6 of the warp-beam is connected by a dog 12 with one of the arms of a gear-wheel 13, whichis attached to the hollow shaft 4: and engaged by a pinion 14 on one end of the shaft 15, journaled in bearings within the bed 1, and carrying at its opposite end a gear 16, which is engaged by a pinion 17 on a counter-shaft 18, journaled in brackets 19 19, which project from the side of the bed 1.

Turning loosely upon -the counter-shaft 18 is a cone-pulley 20, provided with steps 21 22. The cone-pulley is provided with a hub carrying a pinion 23 and having clutch-teeth 24: engaging similar clutch-teeth on the hub 25 of a gear 26, which has a spline connection with the counter-shaft 18 and is capable of a sliding movement on the shaft by means of a hand-lever 27 engaging a neck on the hub 25, and pivoted at its lower end upon a bracket 28, projecting from the side of the bed 1.

One of the bearings 19 at the end of the counter-shaft 18 serves to limit the sliding movement of the gear 26 on the shaft 18 as the clutch-teeth are disengaged. J ournaled within the bracket 28 is a shaft 30, carrying upon one end a gear 31 and on the opposite end a pinion 32. The gear 31 engages the pinion 23 and the pinion 32 engages the gear 26 when it is brought against the fixed bearing 19.

The cone-pulley 20 is driven by a belt connection from a similar cone-pulley on an overhead shaft, the steps'21 and 22 allowing two different speeds to be given to the conepulley 20. By bringing the clutch-teeth on the hub 25 into engagement with the clutch-teeth 24 the rotation of the cone-pulley 20 is communicated directly to the shaft 18 and through the intermediate shaft 15 to the gear 13 and connected Warp-beam but when the gear 26 is moved against the bearing 19 the clutch is separated and the gear 26 is brought into engagement with the pinion 32, causing the rotation of the cone-pulley to be imparted to the counter-shaft 18 through the intermediate shaft 30 and with a reduced speed. I am therefore able to rotate the warp-beam at four different speeds, two speeds being obtained by means of the steps 21 and 22 with a direct connection between the cone-pulley 20 and the shaft 18 and two speeds by means of the steps 21 and 22 with the cone-pulley 20, connected with the shaft 18 through the intermediate shaft 30,.and the speed of the warpbeam can be decreased at different periods in the process of winding in order to maintain approximately the same circumferential speed of the winding-surface as the beam increases in size.

v Arms 33 33, attached to one side of the bed 1, extend upwardly and carry in their upper ends a roll 34, over which the warp-threads 9 are conducted to the rotating beam between the barrel 8 and the compressing-roll 35, which rotates in contact with the warp 9 as it is wound upon the beam. The compressorroll 35 is held in the arms 36, which inclose a little more than half of the periphery of the compressor-roll and are attached to a rocking shaft 37, carrying a segmental gear 38, which is engaged by a similar segmental gear 39 on a rocking shaft 40. The rocking shaft 40 is provided with an arm 41, extending horizontally toward the bed 1, with its end 42 turned vertically upward, and also with an arm 43, which extends vertically upwardand is connected at its upper end with the upturned end 42 of the arm 41 by a bar 44, forming a way or track for the sliding block 45, to whicha nut 46 is attached engaging the threads of a screw 47, journaled in the arm 43 and the upturned end of the arm 41 and provided with a crank-arm 48, by which the screw may be rotated for the purpose of sliding the block 45 along the track 44. The block 45 carries the scored pulleys 49 and 50, connected by a cord or chain 51 with the scored pulleys 52 and 53, carried in blocks 58 and 59, suspended from a cross-bar 60, which is supported upon upright posts 61. 61, held at their lower ends by the framework of the machine.

One end of the cord or chain 51 is attached to a pulley-block 58, and after passing around the pulleys 49 and 52 53 itis connected at its opposite end with a weight 62, causing a pulling strain to be exerted on the arm 41, thereby tending to rock theshaft 40, and also by means of the segmental gears 39 and 38 to rock the shaft 37 and carry the roll 35 against the warp 9 as it is being wound upon the warp-beam. The pressure exerted by the roll 35 upon the warp can be varied by either increasing or diminishing the weights 62 and also by moving the block 45 along the track 44, thereby varying the radial distance at which the pulling strain of the weight 62 is applied to the arm 41. The rocking shafts 37 and 40 are supported upon brackets 63, bolted at one end to the under side of the bed 1 and provided with feet 64, which rest upon the floor.

The rocking shaft 37 is j ournaled in sleeves 65 65, which are held in plates 66, having an opening 67 on their upper side equal to the diameter of the rocking shaft 37, so that by' sliding the sleeves 65 lengthwise on the shaft 37 and withdrawing them from the plates 66 the shaft 37 may be removed through the openings 67. When the sleeves 65 are in position in the plates,66, they are held from longitudinal movement by their flanges 68, which are interposed between the plates 66 and cotter-pins 69, inserted in the shaft 37.

The plates 66 are attached to the flanged steps 70 and are horizontally adjustable thereon by means of bolts 71, which pass through slots 72 in the flanges 73 of the step 70 and holes in the plates 66. The steps 70 are provided with screw-threaded stems 74, which enter screw-threaded holes in the bracket 63, which allows each end of the rocking shaft 37 to be raised or lowered in order to bring the axis of the compressing-roll 35 into the same plane as the axis of the warp-beam, while the horizontal adjustment of the plates 66 on the steps 70 allows the axis of the compressing-roll 35 to be brought parallel with the axis of the warp-beam.

The rocking shafts 37 and 40 are supported upon the brackets 63, which are bolted to the bed 1, and the upright posts 61, which support the upper pulley-blocks 58 and 59, are attached at their lower ends to the framework of the machine, and the entire operating mechanism is therefore contained in a single framework, so that when the operating parts are once adjusted relatively to each other the entire mechanism may be moved into any desired position.

Connected to one end of the rocking shaft 40 and preferably attached to one side of the arm 41 is a hollow segmental ratchet 75, having ratchet-teeth 76 on its circular side. The hollow ratchet 75 is open on its toothed side for the insertion of a lever-handle 77, which is provided with a short slot 78 in the end inserted in the ratchet, and passing through the slot 78 is a pin 79, held in the ratchet 75, thereby allowing a slight endwise-sliding movement of the lever-handle 77 on its pivotal pin 79. The lever 77 carries a pin 80, projecting upon the opposite sides of the handle and adapted to engage the ratchetteeth 76 when the lever-handle 77 is pushed into the ratchet and to be disengaged from the ratchet-teeth by the opposite movement of the lever-handle on the pin 79.

By raising the lever 77 and sliding it on the pin 79 the pin 80 can be carried into engagement with the teeth 76 to give the proper elevation to the free end of the lever-handle. The depression of the lever 77 will then rock the shaft 40, thereby raising the weight 62 and rocking the shaft 37 to carry the roll 35 out of contact with the warp on the warp beam in order to allow access to the warpthreads between the warp-beam and the roll 35 for the purpose of mending broken ends or allowing the removal of the warp-beam when filled, and the roll can be permanently held away from the warp by carrying the le ver 77 under a hook 80 attached to the end of the bed 1.

' The roll 35 rotates in contact with small friction-rolls carried in the arms 36 and indicated by the broken lines 81 and is of the proper length to extend between the heads 6 and 7 of the warp-beam.

The friction-rolls 81 at each bearing-point of the roll 35 comprise two or more rolls of the same diameter rotating abouta common axis, as shown in central sectional view in Fig. 9, where the set of rolls forming one of the bearings of the roll 35 consists of the three rolls a, b, and c of the same diameter. The central roll a is provided with hubs on each side, on which the side rolls b and 0 turn.

When a single roll is employed, it is liable to become worn in spots on its periphery, causing an irregular motion of the compressing-rolls as it comes in contact with the worn spots, and this difficulty is overcome by using a multiplicity of rolls with each capable of independent rotation. In case one of the rolls becomes worn out of round the compressing-roll will be supported on the peripheries of the remaining rolls as it passes over the worn spot, and should portions of each roll become worn out of round the worn spots of each must coincide to effect the movement of the compressing-roll.

The entire mechanism for rotating the warpbeam and applying pressure to the warp-compressing roll is located upon the back side of the warp-beam, leaving the front and upper side of the warp-beam entirely free for the attendant and providing a free space for the removal of the warp-beam.

The shaft 18 carries a ratchet 82, which is engaged by a pawl 83, pivoted upon the fixed framework of the machine, in order to check the reverse movement of the warp-beam. A spring 84 incloses the shaft 18, with one of its ends 85 engaging the pawl 83, so that when the shaft 18 turns in one direction the end 85 of the spring will be thrown down by the frictional contact between the spring 84 and the shaft 18, thereby rocking the pawl 83 and carrying it into engagement with the teeth of the ratchet, while the movement of the shaft 18 in the opposite direction will raise the pawl '83 out of engagement with the ratchet, so that the end of the pawl will not ride on the ratchet-teeth while the warp is being wound.
